Dayon! is an easy-to-use, cross-platform remote desktop assistance solution.

It consists of two parts - one for the assistant and one for the assisted. Both are included in one single package.
As quick launch versions for Windows, they are also available as individual binaries, as snap, flatpak or nix for various linux distributions.

Key features

• easy setup (no router or network configuration needed on the assisted side)
• intuitive, multilingual user interface (de, en, es, fr, it, ru, sv, tr, zh)
• assistant and assisted functionality in one package
• secure, end-to-end encrypted communication (TLS 1.3)
• very low bandwidth usage
• cross-platform
• open source
• free (as hugs)

History

Dayon! was originally developed by Marc Polizzi back in 2008.

With his consent, I have taken over the maintenance and further development of this software in late 2016.
I also moved the code base to GitHub, where it can easier be maintained.

Releases

The is v16.0.0 (Eager Eagle) - released more than ten years after the initial release.

While v15.0.0 was the first version in which the remote desktop could also be transmitted in colour - in addition to the bandwidth-saving greyscales,
this one comes with the ability of automatically reversing the connection establishment in cases the assistant side is blocked by a NAT or firewall.

Contributors

Any feedback and contributions are very welcome.

You don't have to be a programmer!

For example translations for additional languages would make this app more useful for more earthlings - see: src/main/resources/Babylon.properties or docs

Also, improvements of the existing translations and documentation are very welcome! As my knowledge of Chinese is far below zero - and my knowledge of Russian or Turkish just fractions better..

Further testing, especially on macOS with silicon (M series) would also be greatly appreciated.
